At the recent Citrus & Specialty Crop Expo, Ozgur Batuman reminded seminar attendees there is no silver bullet for HLB management. Instead, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher proposes that growers integrate several tools for the management of HLB. These tools include a variety of ways to control HLB-spreading psyllids; oxytetracycline (OTC) trunk injection; …
Federal and state officials recently expanded the area quarantined for citrus greening disease, also known as huanglongbing or HLB, in California. They expanded the quarantined area in the San Clemente area of Orange and San Diego counties by 81 square miles. The action was taken by the U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) in cooperation …
Residential trees — where citrus greening disease (also known as huanglongbing or HLB) was first detected in the Florida — can serve as reservoirs for disease-spreading Asian citrus psyllids (ACP) if the pests are not properly managed. Recognizing that disease prevention is a coordinated effort, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is teaching Florida residents …
The annual Citrus Grower’s Summer Update meeting on Aug. 14 in Valdosta, Georgia, provided cold-hardy growers with updates on several factors impacting the industry. Information on topics ranging from snails to phytophthora to Asian citrus psyllid trapping were presented to growers who are on the cusp of harvesting another season’s crop. Jake Price, University of Georgia (UGA) area citrus agent …
The Citrus Research and Development Foundation (CRDF) met for its July board of directors meeting to discuss a number of research topics. According to CRDF Chief Operating Officer Rick Dantzler, Asian citrus psyllids (ACPs) were on the agenda. “The CRDF board approved funding of a proposal from Lukasz Stelinski, an entomologist and professor with the University of Florida Institute of …
Native to South America, Argentine ants were introduced to California in 1905. Today, 90% of Southern California and coastal orchards are infested with ants. Some trees experience up to 1 million ant visits per day. Ivan Milosavljević, Citrus Research Board (CRB) entomologist, presented that information in a June 17 webinar that was part of CRB’s Grower Seminar Series. His presentation …
Federal and state agriculture officials recently expanded the areas quarantined for huanglongbing (HLB, also known as citrus greening) disease in California. The quarantined area in the Foothill Ranch and Mission Viejo areas of Orange County has been expanded by 26.69 square miles, the Riverside area of Riverside County by 11.3 square miles, and the Valley Center area of San Diego …
The U.S. Department of Agriculture National Institute of Food and Agriculture (USDA/NIFA) announced May 28 it has invested nearly $23 million in 14 HLB projects in 2025. The projects seek to find solutions to combat and prevent HLB in citrus. The projects are part of the Emergency Citrus Disease Research and Extension Program. The University of Florida is the only …
By Lauren Diepenbrock Red imported fire ants (Solenopsis invicta), commonly referred to as fire ants, are found throughout Florida. This pest infests a broad range of habitats, including urban regions, natural areas and production fields. In citrus, there are a range of impacts from this pest — from human health to both direct and indirect tree impacts. From a human …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center hosted an OJ Break seminar on May 14. The speakers provided updates on developing a gene-edited citrus tree with resistance to HLB and how growers can use existing tools to mitigate the disease. Nian Wang, UF/IFAS professor, provided an update on the status of …
Carlton Collins recently was named top master’s researcher in the E. Broadus Browne Research Awards for Outstanding Graduate Student Research competition at the University of Georgia (UGA) College of Agricultural and Environmental Sciences. He was recognized for his research on huanglongbing (HLB) disease, also known as citrus greening. Collins, born in Jamaica, was introduced to citrus production on a small …
By Jawwad A. Qureshi Several insect pests and mites colonize citrus crops in traditional open orchards. Most pests are localized and are suppressed by predators, parasitoids and entomopathogens to levels that are not economically damaging to the crops. The Asian citrus psyllid (ACP) is the primary vector of huanglongbing (HLB) disease. Despite biological and chemical control of ACP, growing a …
Growers use the citrus under protective screen (CUPS) production system to protect trees from the Asian citrus psyllid, the insect vector of HLB disease. While grapefruit is most commonly grown in CUPS, statistics support the belief that CUPS can be conducive to other types of citrus. “There’s a need to establish the growing requirements and the needs of other varieties. …
The California Department of Food and Agriculture (CDFA) declared a citrus quarantine expansion in San Diego County’s Valley Center on March 26. The expansion occurred after detection of HLB disease in two citrus trees in residential neighborhoods in the Valley Center area during regular inspections. HLB is a major threat to San Diego County’s $144 million annual citrus crop …
It is much better for Florida citrus growers to be proactive than reactive when managing pest populations. Scouting and monitoring citrus groves is crucial for growers who hope to thwart off impacts from insects like the Asian citrus psyllid (ACP). If growers are not successful, they will be behind the eight ball in minimizing the impact of these annual pests. …
Federal and state officials have expanded the quarantine for huanglongbing (HLB, also known as citrus greening disease) in the Mission Viejo area of California’s Orange County. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture, expanded the quarantine by 13.16 square miles. The expansion was in response …
A tool predicting how to protect European citrus from HLB shows how mathematical modeling can help prepare for future plant disease invasions. Europe is currently unaffected by HLB. However, there are increased concerns of an infestation since psyllids that spread HLB have been found in key citrus-producing countries, including Portugal and Spain. In response to the HLB threat, a new …
The California Department of Food and Agriculture (CDFA) recently announced the expansion in Orange County of an emergency program for HLB and the Asian citrus psyllid (ACP) that spreads the disease. The expansion follows confirmation throughout January of the causative bacterial agent of HLB in plant tissue and/or ACP in Anaheim, Costa Mesa, Garden Grove, Irvine, Mission Viejo, Orange, Santa …
HLB was recently confirmed for the first time in Arizona, first in an Asian citrus psyllid (ACP) and then in another ACP and citrus plant tissue. The Arizona Department of Agriculture (AZDA) reported the details. On Dec. 16, 2024, agriculture inspectors collected ACP and plant tissue samples from a residential citrus tree in Nogales. The collections were made during a …
The Florida Citrus State of the Industry Survey seeks input from growers on key issues affecting their groves. The survey has been conducted for many years, has tracked the trajectory of HLB and reported on production practices. While not a scientific survey, it has reflected general trends over the years. Last month, we published results on trunk-injection therapy and the …
